25.203(l) Analysis for 17/24 GHz BSS Feeder Link Antenna In this application, DIRECTV Enterprises, LLC (“DIRECTV”) requests, in part, operating authority to allow an earth station antenna at DIRECTV’s new Bakersfield, CA uplink facility (LA/BF) to communicate with DIRECTV RB-1 and DIRECTV RB-2, the 17/24 GHz BSS communications payloads on the DIRECTV 14 and DIRECTV 15 satellites, respectively. Under Section 25.203(l) of the Commission’s rules, 47 C.F.R. § 25.203(l), feeder link facilities operating in the 25.05-25.25 GHz band can only be licensed in Economic Areas (“EA”) where no existing FS licensee is authorized, and feeder link operations must be coordinated with FS licensees in nearby EAs when the PFD of the feeder link transmitted signal is equal to or greater than -114 dBW/m2/MHz at the boundary of the FS licensed area. DIRECTV notes that the earth station that is the subject of this application is located in Kern County, CA, which is in EA 160. According to the Commission’s ULS database, there are no FS licensees in that EA authorized to operate in the relevant band. The table on the following page was produced as a result of a search of the ULS database for authorizations to operate in the 25.05-25.15 GHz band. As can be seen, there are five active licenses in this frequency band and twenty six pending applications, and the Market/Area for each is shown. As can be readily determined, the Market/Areas for all licenses but one are well removed from Kern County, CA and from DIRECTV’s Bakersfield location. The one exception is call sign WPNH294 in Stockton, CA, which is in EA 163. An analysis of EA 163 shows that Monterey County, CA is the closest county in EA 163 to DIRECTV’s Bakersfield location. A Google Earth search of California counties surrounding Kern County resulted in the image on the following page. As can be seen, the shortest distance from DIRECTV’s Bakersfield site to Monterey County, or the edge of EA 163, is just over 72 miles. The analysis below demonstrates that the applied for earth station will meet the -114 dBW/m2/MHz level at the boundary of EA 163 with over 15 dB or margin. 13.2m uplink Monterey 24 GHz BSS Feeder Link Antenna Parameters Co Max EIRP/carrier (dBW) 80.0 Antenna size (m) 13.2 Antenna on-axis gain (dBi) 67.0 Max power into antenna (dBW) 13.0 Bandwidth normalizing factor for 36 MHz carrier (dB) 15.6 Max power density into antenna (dBW/MHz) -2.6 Max gain towards the horizon (dBi) (§25.209) -10.0 Max eirp density towards the horizon (dBW/MHz) -12.6 Min distance to EA border (km) 115.2 Spreading loss over min distance to EA border (dB- m2) 112.2 Max PFD at EA border (dBW/m2/MHz) -124.8 Margin in DEMS protection (dB) 10.8 1
